Problems solved by technology

However, for some shell parts, since they are non-revolving parts, the hole processing cannot be achieved with a general-purpose self-centering clamping mechanism.
The traditional method is to use the process method of sub-process processing. Multiple processing equipment will be used to complete the processing of one part. Therefore, the labor intensity is high, the auxiliary time of part processing is long, and the production efficiency is low.
More importantly, with the manual clamping method, it is not easy to guarantee the machining accuracy of the parts and the consistency of the parts size, and it is easy to produce waste products and unqualified parts

Abstract

The invention discloses a hydraulic power fixture of a numerical-control machine tool, which belongs to the field of machining and comprises an oil cylinder, a draw bar, a transitional plate and a fixture body. A pressure plate and a pressure claw shaft are arranged in an inner cavity of the fixture body, the pressure claw shaft is meshed with the outer edge of the pressure plate, a guiding groove is disposed on the pressure claw shaft, and the pressure claw shaft peripherally swings while moving axially under effects of the guiding groove and a guiding screw. The hydraulic power fixture is novel in structure, and firmly and stably clamps a shell part effectively, machining precision can be effectively guaranteed, machining auxiliary time of the part is shortened, and work efficiency is improved. In addition, the hydraulic power fixture can clamp different parts by means of adjusting the structure of the pressure claw shaft and the size of a pressure head, and accordingly is wide in applicability.

Description

technical field [0001] The invention relates to the field of numerical control machine tool equipment, in particular to a hydraulic power clamp of a numerical control machine tool used for processing shell parts. Background technique [0002] In the machinery manufacturing industry, CNC machine tools, especially CNC lathes, are widely used to process disc and shaft parts. During the processing of conventional rotary parts, many parts need to use the end face and inner hole as the positioning clamping surface for cutting the outer circle, end face, thread and axial cutting. This kind of parts processing, especially the outer circle, end face And threads, etc. There are many traditional clamping and positioning mechanisms to meet the requirements of use. And for some shell parts, because the hole processing of non-revolving body parts, it cannot be realized with a general self-centering clamping mechanism. The traditional method is to use the process method of sub-process pr...
